Although enrollment in journalism schools is down slightly by 1 percent, it remains a popular choice for many recent high school graduates, according to the 2011 Annual Survey of Journalism and Mass Communication Enrollment. The combination of fewer people choosing journalism, coupled with more journalism programs such as digital journalism and public relations, has lessened competition to get into a journalism program. However, high school students still need to prepare.

AP/Advanced English

In addition to journalism coursework, English and writing classes are required to further develop a potential journalist's skills.Reporters write stories, photojournalists write captions and copy editors write headlines. The more exposure a student has to writing, the better he will be able to write quickly and effectively.High school students should explore advanced and AP English courses. These give high school students a more in-depth opportunity to think critically about their writing and develop the skills to analyze other writers.

School Newspaper or Yearbook

The most practical experience a student can receive is on the school's newspaper or yearbook staff. This after-school activity or class allows students to learn to write on deadline, prepare well-written, thoughtful stories and develop interviewing skills.This activity is also a great choice for aspiring photojournalists who want published clips of their photos.Newspaper and yearbook activities will also add clout to a college application to a journalism school. If the student has a strong relationship with the adviser of the club or class, he can ask the adviser to write a reference for his college applications.

Math Courses

In general, aspiring journalists aren't hoping to spend most of their college studies in math courses. Most colleges don't require journalism students to take statistics courses, reports Justin Martin of the "Columbia Journalism Review." However, journalists' math skills are increasingly being tested, and those who can properly interpret data can have an edge. Martin, a journalism professor at Northwestern University, argues that "statistics is too pressing a global language for journalists to neglect."

Other Classes

Traditionally, general education courses in most journalism schools might include study of a foreign language, political science and history. However, some colleges are revamping their curriculum because of recent changes to the way people receive news.For example, Columbia's Journalism School is incorporating more digital and blogging-focused required courses, reports "Crain's New York Business."
